echoMAP 54dv includes a 5-inch high-contrast color display with automatic backlight adjustment. Fast, responsive 5 Hz GPS/GLONASS refreshes your position and heading 5 times each second to make your movement on the screen more fluid. echoMAP comes with 1 transducer for 77/200 kHz HD-ID sonar and Garmin DownVü™, the clearest scanning sonar on the water. It also supports Minn Kota® and MotorGuide® trolling motors with integrated transducers. The combo's cords plug directly into the mount, allowing you to quickly install and remove your device from power and the mount. Transom and trolling motor mount included.Clearest Scanning Sonar on the WaterGarmin DownVü™ scanning sonar gives you a nearly photographic image down to 750-feet below your boat. You clearly see structure, submerged objects and fish! Traditional Garmin HD-ID sonar and DownVü scanning sonar are combined into one transducer. Also provides HD-ID support for Minn Kota and MotorGuide trolling motors with integrated transducers. The echoMAP 54dv also includes sonar-recording capability that coordinates the timing of the sonar return with your boat's position and saves digital information for playback on a computer using free HomePort™ planning software. Use the User Data Sharing Cable to share waypoints and routes between multiple devices.Preloaded BlueChart g2 mapsCovers the coastal U.S. and Bahamas – East Coast, West Coast, Gulf of Mexico, U.S. side of the Great Lakes. Includes all U.S. Charts for the entire coastline and the Bahamas. Includes everything available on NOAA charts. In addition to the basic charts, tidal stations, currents, depth contours, IALA symbols and included fishing charts, BlueChart g2 offers smooth transitioning between zoom levels and more seamless continuity across chart boundaries. You can customize your screens with Safety Shading which allows you to contour shade for all depth contours shallower than what you determine is your safe depth. Fishing charts emphasize bathymetric contours with less visual clutter on the display. And there’s also a choice of standard 2-D direct overhead or 3-D “over-the-bow” map views for easier chart reading and orientation.Heading and Position Refreshed 5 Times per SecondFast, responsive 5 Hz GPS/GLONASS refreshes your position and heading 5 times each second to make your movement on the screen more fluid. It makes dropping up to 5,000 accurate waypoints and finding your way back to your secret fishing hot spots quick and easy.Take Your echoMAP with YouWhen you’re off the water, it’s easy to keep your echoMAP safe and secure. You don’t have to mess with plugging and unplugging wires from the unit because the cords plug directly into the mount. This allows you to quickly install and remove your echoMAP from power and the mount.Upgrade with the Best Garmin Maps on the WaterA single microSD™ card slot provides expandable memory for accessory map purchases such as LakeVü™ HD, LakeVü HD Ultra or BlueChart g2 Vision. LakeVü HD Ultra and BlueChart g2 Vision provide exclusive Garmin Auto Guidance that directs you right to your hot spots by instantly creating an on-screen path based on your boat’s specifications that you can follow to avoid shallow water and other charted obstructions.Enhanced Auto GuidanceJust enter the location where you want to go and patented Garmin Auto Guidance technology instantly searches through relevant charts to create a safe virtual pathway on the display that helps you avoid low bridges, shallow water and other charted obstructions en route.

Better still, with enhanced Version 2.0, you now have access to even more features and capabilities. You’re able to adjust the calculated Auto Guidance pathway by inserting “via” points at interim stops or landmarks along your desired route. You can easily review hazard points along your calculated path. And you can even engage your compatible Garmin autopilot to follow the Auto Guidance route, automatically. Other 2.0 enhancements give you the ability to calculate arrival times at any point on your route (great for timing arrivals to correspond with bridge openings and other time-critical events). Better still, you can now save your plotted Auto Guidance paths for future navigation by backing them up on an SD™ card with your BlueChart® g2 Vision® or Lake Vü™ HD Ultra cartography².GPX Waypoints TransferIf you have waypoints, tracks or frequently used routes stored on another manufacturer’s GPS product – or on a Garmin handheld device – now it’s easier than ever to transfer those items to your new Garmin chartplotter, via industry-standard GPX software formatting. GPX is an open standard format for GPS data exchange across platforms and applications. With this easy-to-use interface technology, Garmin has taken “no waypoint left behind” to a whole new level of trade-up convenience.

¹Applies to versions with transducers only. No transducer versions support 50/200 kHz, 77/200 kHz and Garmin DownVü/SideVü transducers, sold separately. See transducer selection guide for complete list of compatible transducers.2BlueChart® g2 Vision® or LakeVü™ HD Ultra SD card is required for this technology.
